反応手順
A mixture of tert-butyl-N-[1-[(1-bromoisoquinolin-3-yl)amino]-1-oxopropan-2-yl]-carbamate B4a (150 mg, 0.38 mmol), 3-ethynylthiophene (45 mg, 0.42 mmol), copper(I) iodide (7 mg, 0.04 mmol), Dichlorobis(triphenylphosphine)palladium(II) (27 mg, 0.04 mmol) and DIPEA (200 μl, 2 mmol) is stirred under argon atmosphere in NMP (1 ml) for 1 h at 80° C. The mixture is concentrated in vacuo and the product purified by RP HPLC. Yield: 102 mg (64%). HPLC-MS: M+H=422; tR=1.99 min (*Method—4).
